Auction previews
The October 10 auction at New York’s Arader Galleries includes the collection of the surgeon Dr Seymour Schwartz (2020) – a map collector Graham Arader considered something of a mentor. When in the 1980s Arader developed a grading system for maps and prints based on the four pillars of historical importance, aesthetics, condition, and rarity, it was Schwartz who he asked to refine the rules.
